What type of header bolts right into the ITR catback exhaust? I currently have that exhaust on my car and was looking to get the JDM 4-1, but it has a 2.5" collector on it. any suggestions/ideas?

 

get the jdm 4-1 header and take it to a reputable place to get a flange welded on and ur good to go

 

buy a Rev Hard manifold. quit ****** with stupid 5 horse power baby stuff.

 

That's what I'm doing. I just ordered a DC JDM 4-1 today.

Although, I do have a quick question. Eventually I'm going to get a high flow cat (2.5"). I won't have any flange fitment issues with that, will I? 2.5" collector to 2.5" cat... the flanges should bolt right up, correct?

Just inquiring to be sure for future reference while the subject is brought up.

Thanks

 

get a 2.25 inch one end and 2.5 inch other end carsound cat. then get a dc jdm 4 to 1 header..that way it will all bolt right up.
